Step1
Start early. As a matter of fact, you can start communicating with signs as soon as you bring your new baby home.
Step2
Purchase a book of basic signs for children. There are plenty of options out there, but to start you only need a board book with the basics.
Step3
Start early. As a matter of fact, you can start communicating with signs as soon as you bring your new baby home.
Step4
Pick two or three signs that are simple and you need to express to your child often. Good ones to start out with are the signs for diaper, milk, more, Daddy, Mommy, eat, sleep, bath or any other word you like and use often.
Step5
Look your child in the eye and say the words while you are signing them. For example, if baby needs to be changed, look in his or her eyes, do the sign for diaper and say "do you need a new diaper?" Or if they are hungry, say "would you like some milk?" while signing milk.
Step6
Be patient and persistent. Infants are incredibly smart, and will understand what you are saying and signing long before they can mimic you.
Step7
Pay attention to your child's responses and reactions. Before you know it, your child will respond by doing the sign or their own version of it (be sure to let your child do their version of the sign... their ability to sign will grow just like their verbal communication skills.)
Some babies are able to start copying signs as early as six months, but all children have their own timetable for what they can do.
Step8
Once your child begins doing a couple signs, expand the words that you sign and say to your child. At this point, you can also introduce more fun signs like different animals, or even teach them to say please and thank you.
If you think of a word you would like to know the sign for, take advantage of the Internet. There are plenty of sites out there with ASL (American Sign Language) words with pictures and diagrams.
